Tom Posted March 1, 2018 Report Share Posted March 1, 2018 The active pattern continues to roll in the first full week of March with another large scale system ejecting out of the Rockies and slowly bowling its way through the central CONUS. This will be a widespread and far reaching storm that will likely initially bring a swath of accumulating snows into the Upper MW and parts of the Plains. Once cold air wraps into the system, snow may mix in into the MW/GL's region. Let's discuss... 12z ICON... 12z GGEM... Quote Link to comment Share on other sites More sharing options...

NWS Hastings really talked this up in their afternoon disco yesterday, then downplayed it this morning. I wonder if some of this new model data may get them talking again. These type of storms are tough to predict and forecast in that they don't always go the direction that we expect, west to east, southwest to northeast, etc. Some actually can retrogade. I am just hoping for some good moisture for our area out of this. 1 Quote Link to comment Share on other sites More sharing options...

Tabitha has been discussing it for the last two weeks...lolz I am sensing that there is going to be a very, very large snowstorm around here (western SD) around Day 14 / March 3. We'll pull the post in 2 weeks to see if I was Right or Wrong. There is not too much meteorology in this particular prediction of mine; just an innate sense. Someone once asked Me; "Did you ever have a conversation with yourself?" I smartly replied,"Those are my favorite ones; as I am the only one who does what I tell them to do."

CentralNebWeather Posted March 1, 2018 Report Share Posted March 1, 2018 I sure hope this tracks a little farther south, if for nothing else the beneficial rainfall that could occur. Very fearful of the dreaded "dry slot". NWS Hastings mentioned it this morning. CMC is farther north and ICON and GFS are the furthest south. Euro was north at 0Z. Need to see what the 12Z shows.

Tabitha Posted March 1, 2018 Report Share Posted March 1, 2018 12z Euro also suggest the month's 1st Blizzard across the Dakotas...EPS is north, GEFS are farther south...let the battle begin... Both the 12z control run and operational ECMWF have about 0.4 LE here over 48 hours....which would not be terrible. The Rapid City NWS WFO was able to somehow accumulate 11 inches of snow on 0.45 LE two weeks ago (about 24:1); so it doesn't take a lot.

CentralNebWeather Posted March 2, 2018 Report Share Posted March 2, 2018 SPECIAL WEATHER STATEMENTISSUED: 2:58 PM MAR. 1, 2018 – NATIONAL WEATHER SERVICE...A Strong Spring Storm System will Impact the Region Sunday andMonday... A complex and potent low pressure system will evolve over thecentral Plains Sunday and Monday. A cold front will sweep throughthe region Sunday evening...possibly triggering the firstthunderstorms of the season during the late afternoon and evening.As colder air rushes in behind the front...there is some limitedpotential for snow Sunday night. Very high winds will then developMonday behind the system. Some areas could see sustained windsnear 40 mph at times...with gusts of at least 60 mph. Thethunderstorms and snow may affect only portions of the area...butthe high winds will affect the entire area. Winds that high canproduce damage...including blowing down trees and power lines. Everyone should closely monitor future forecasts and be preparedfor variable and potentially hazardous weather Sunday and Monday.For the latest forecast information...visit weather.gov/hastingsor listen to NOAA Weather Radio.

St Paul Storm Posted March 2, 2018 Report Share Posted March 2, 2018 Tabitha is definitely in the best spot in this forum to see a good snow. No idea what to expect here. Looks like a combo platter of rain, snow, and possibly freezing rain if we get close enough to the dry slot. Might have some flooding issues if the majority of precip is rain. 1 Quote Link to comment Share on other sites More sharing options...

Tabitha Posted March 2, 2018 Report Share Posted March 2, 2018 Absolute consensus on the 12z suite thus far {NAM, Canadian, GFS, ICON} that EVERYWHERE...to my north, south, east & west...will do far, far, better than here. Never have I seen such model uniformity! On the good side; the models have not been bad this year in these Hills; they have been unbelievably awful; even while snow events were in progress. Also, it is still 60 hours out. The ECMWF comes out in an hour; that is the ONLY model that is able to decipher this area; (to some extent). We'll see what it shows.

As I have written previously; the ONLY thing you can rely on around here when a storm approaches is CLIMATOLOGY. I am not in the best snow area; but I am likewise a good deal snowier than the plains of SD off to the east. I'm pretty sure that will find a way into the equation; before all is said and done. First rule of forecasting; you cannot fight climatology; be it good...or bad. 1 Quote Link to comment Share on other sites More sharing options...

Never have I seen such model uniformity! Actually; there is some dissent; the NAVY / NOGAPS is very snowy here; right into Tuesday...I wrote a post about 3 months ago commenting on how that model actually has been pretty good around here a few times. I'll see if I can ferret it out... Yes, here it is: NOCRAPS NOGAPS now has the quoted system in here a bit slower...not until very late Friday; but a nice short wave / overrunning event as a clipper rides the front setting up east of the mountains...with about 30 straight hours of snow; some of it moderate. The Navy model & UKMET have done very well here so far this winter; far better than their more storied & celebrated counterparts. The late December storm in question with the "30 hours of snow"...only amounted to 2.5 inches of actual snow here...so so much for that...lol.

Thats not something you see everyday. But it’s causing model havoc that’s for sure.

Not 100% certain; but I do believe the block in the atmosphere that will cause the stall / retrograde is directly correlated to the Negative Stage of the North Atlantic Oscillation / (NAO); as it has been falling sharply since Feb 27.

Now from this...per what little I know on the subject....is that a reflection at higher levels of general low pressure develops over the Eastern Sections of Canada; and yes; a sort of bowling alley of storms circulates around the bottom of the Large Upper Low. This blocking action over Quebec and the Canadian Maritimes; very much the antithesis of the quick westerly & zonal flow that we saw in January; allows for storms to both slow and strengthen...gathering Gulf Moisture; and therefore yield far greater amounts of snow & rain.
